法華論疏 1.156

1.156

四名教菩薩法者，至法華時回小入大，及直往菩薩根皆已熟，故下云「如來涅槃時到、眾又清淨」也。

"Fourth, it is called the Dharma for Instructing Bodhisattvas": by the time of the Lotus, both those who turn from the small to enter the great and direct-progressing bodhisattvas have all matured their faculties; therefore it says below, "The time for the Tathāgata's nirvāṇa has arrived, and the assembly is moreover pure."
